If the rod is made longer it will speed up that side

t side needs to go slower (by shortening the

rod). If the mower is tracking to the right, either
the right side needs to go faster (by lengthening
the rod) or the left side needs to go slower (by

ortening the rod). It is important that neither rod

should be lengthened too far, as mentioned
above.

everything is way off either because you are

talling new parts (or other reasons) you should

only use the faster Speed/ Sensitivity setting to
get the tracking accurate and then change to the

Tire Maintenance and Pressure

Excessively worn tire tread is dangerous on all
hills. Replace drive tires with less than 3/32” of
any tread groove left. Use tires with the tread
pattern recommended by Wright Mfg., Inc. only.

Adjustment

the mower

hydraulic motor supports may be used to make a
fine forward/rearward adjustment to the balance
of the Velke Mower. This adjustment should
always be made in combination with the coarse
height-of-cut adjustment and anti-tip roller
adjustment as described below. When the motor
supports are set in the forward position, the Velke
Mower will be balanced lighter in the front than
when set in the rearward position, giving more
traction to the drive tires. Heavy operators (over
